I have an Lg Optimus S. It has been a real trooper. Drops, washings, kids and no problem what so ever. I am also changing carriers so I am hoping for the best with the DNA. It looks like it will be killer. Batteries don't worry me either.
I guess I'm just used to the TB, I know what all the settings are, I know exactly the places where it fits perfectly (in my car, jacket, etc.), it's durable, etc. If I was stock I would hate the TB.
But I guess it comes down to having to pay full retail, if I need to spend $600-$700 for a phone it better blow my TB out of the water, which so far nothing has.
